Allocation query rules. The enum uses the following naming convention: A, B, C, D = time markers a = time when "alloc" event occurs f = time when "free" event occurs (can be infinite) Ex.: "AaBf" means "all memory allocations allocated between time A and time B and freed after time B".
enum EQueryRule { aAf, afA, Aaf, aAfB, AaBf, aAfaBf, AfB, AaB, AafB, aABf, AaBCf, AaBfC, aABfC, AaBCfD, }
